I found that there is a 1-second timer running all the time in kdesktop (at least)
due to KStartupInfo.
Am I right that storing a pointer all the time is better than having a useless timer
be triggered every second (in every app using that class - not sure how many that is) ?

Since we append to d->startups at only one place, this is quite easy to do :
